Abstract

PURPOSE:To simplify the operation of function switching, by connecting a transmission cord of an audio signal between an amplifier and an external device like a record player and also with a cord for function designation. CONSTITUTION:The output signal of the record player 10 is connected to the amplifier 11 with the audio signal transmission cord 12. The player 10 has the switch switching the power supply for motors to turn the turn-table, and it is provided with the start switch 13 in interlocking with the switches. This switch 13 is connected between the function designation circuit 1 and ground. When the switch 13 of the player is depressed, the function designation circuit 1 is at ground potential, trannistor 2, 3 are ON, and the output terminal 16 is at L level. This results in the closed switch 15 of the amplifier 11, and the function is switched to the player. With the constitution like this, the operation of the function is simplified.
